Answer :
Answer:
[tex]Length = 18[/tex]
[tex]Width = 27[/tex]
Step-by-step explanation:
Given
Dimension = 20 by 30
Reduction = 10%
Required
Determine the new dimensions
Because it is a reduction, the new dimension is calculated using:
[tex]New = Old (1 - Reduction)[/tex]
The new length is calculated as:
[tex]Length = 20(1 - 10\%)[/tex]
Convert percentage to decimal
[tex]Length = 20(1 - 0.10)[/tex]
[tex]Length = 20 * 0.90[/tex]
[tex]Length = 18[/tex]
The new width is calculated as:
[tex]Width = 30(1 - 10\%)[/tex]
Convert percentage to decimal
[tex]Width = 30(1 - 0.10)[/tex]
[tex]Width = 30*0.90[/tex]
[tex]Width = 27[/tex]
